[0003] Patent CN211741211U provides an automatic detection device for automobile air quality sensors, which abuts the gas detection interface of the air quality sensor to be detected through the air outlet on the cover plate. After pressing the cover plate, it can be completely sealed and the detection gas air, nitrogen dioxide, ammonia and carbon monoxide, etc. are introduced. Finally, the driving mechanism such as the cylinder is started to push the lifting platform upward, and the metal probe is inserted into the air quality sensor to be detected. However, in the process of closing the cover plate, the above patent is difficult to ensure that the air outlet on the cover plate to be detected is fully abutted with the gas detection interface of all the air quality sensors to be detected, and the detection quality of the control quality sensor cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to provide a gas detection structure for rapid detection of an automobile air quality sensor in order to overcome at least one of the defects of the above-mentioned prior art. The detection structure places the air quality sensor on a supporting plate, and after the air quality sensor is pressed by a clamping mechanism, the accurate connection between the airway and the inlet of the air quality sensor and the accurate connection between the electrical connection end of the air quality sensor and the power-on mechanism are ensured, thereby ensuring the detection quality of the sensor.

[0011] A gas delivery mechanism is arranged on the side of the supporting plate, and the gas delivery mechanism includes a forward and backward moving cylinder arranged on the bracket, an airway arranged at the output end of the forward and backward moving cylinder, and a connector arranged at intervals on the airway, and the connector is directly opposite to the gas detection inlet of the air quality sensor.

[0012] Furthermore, the clamping mechanism includes a clamping cylinder arranged on the bracket, a pressure plate arranged at the output end of the clamping cylinder and slidably connected to the bracket, and a plurality of clamping columns arranged at intervals on the pressure plate, and the clamping columns are located directly above the air quality sensor.

[0013] Furthermore, the compression column is an elastic column.

[0014] Furthermore, the pressing plate is provided with reinforcing ribs.

[0015] Furthermore, the power-on mechanism includes a lifting cylinder arranged on the bracket, a lifting plate arranged at the output end of the lifting cylinder and slidably connected to the bracket, and a plurality of metal probes arranged at intervals on the lifting plate, and the metal probes are located directly below the air quality sensor.

[0016] Furthermore, the carrying plate includes two rows of storage holes arranged at intervals, and the air quality sensors are placed in the storage holes.

[0017] Furthermore, the storage hole is a square hole or a circular hole.

[0018] Furthermore, among the two rows of storage holes arranged at intervals, the storage holes close to the bracket are lower than the storage holes far from the bracket.

[0019] Furthermore, the air inlet of the air passage is connected to an air source.

[0020] Furthermore, a pair of slide rails is provided on one side of the bracket close to the rotating disk.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] (1) The present invention provides a gas detection structure for rapid detection of an automobile air quality sensor. The detection structure places the air quality sensor on a supporting plate. After the air quality sensor is pressed by a pressing mechanism, the accurate connection between the airway connector and the inlet of the air quality sensor and the accurate connection between the electrical connection end of the air quality sensor and the power-on mechanism are ensured, thereby ensuring the detection quality of the sensor.

[0023] (2) The present invention provides a gas detection structure for rapid detection of automobile air quality sensors. The detection structure compresses each air quality sensor through a compression column located directly above the air quality sensor. In particular, the compression column can be an elastic column, so that the downward pressing process is a highly controllable and uniform force application process, ensuring that the applied pressure can be evenly distributed on the surface of the sensor; this uniform pressure effect can effectively overcome the problems of looseness or poor contact of the sensor that may occur during the installation process, so that each air quality sensor can be tightly fixed in its corresponding position, thereby ensuring the accurate connection between the subsequent airway connector and the inlet of the air quality sensor and the accurate connection between the electrical connection end of the air quality sensor and the metal probe of the power-on mechanism, thereby ensuring the accuracy and reliability of the detection data.
